CadQuery is a powerful open-source parametric 3D modeling library that offers an innovative way to create 3D models using Python programming language. It is built on top of the widely used 3D modeling kernel, Open CASCADE Technology (OCCT), providing a high-level API for CAD (Computer-Aided Design) tasks. With CadQuery, engineers, designers, and developers can generate complex 3D models programmatically, making it an excellent tool for automating design processes, rapid prototyping, and design optimization. Moreover, CadQuery is based on constructive solid geometry (CSG) principles, allowing users to create models by combining various 3D shapes in a constructive manner, offering greater flexibility and control over the design process.
Key Points about CadQuery:
1. Parametric Design Capabilities: CadQuery empowers users to create parametric models. Parameters can be used to control dimensions, features, and other aspects of the design, making it easy to modify and adapt models as per specific requirements. This parametric approach significantly reduces the design time and enhances design flexibility.
2. Python-Based Scripting: One of CadQuery’s major strengths is its integration with Python, a popular, versatile, and user-friendly programming language. As a result, users familiar with Python can leverage their programming skills to create, modify, and automate 3D models efficiently.
3. Open Source and Free: CadQuery is an open-source project, meaning it is freely available for anyone to use, modify, and contribute to its development. This fosters a strong community of users and developers who continually improve the library and provide support through forums and other platforms.
4. Interactive 3D Visualization: CadQuery includes built-in support for interactive 3D visualization. Users can inspect and manipulate 3D models directly within Jupyter notebooks or through integrated viewers like ParaView. This feature enhances the design process by offering real-time visual feedback.
5. Integration with 3D Printing and CAD Tools: CadQuery provides export capabilities to standard 3D file formats, such as STL (stereolithography) and STEP (Standard for the Exchange of Product model data), making it seamlessly compatible with 3D printing and various CAD software. This integration enables users to smoothly transition from design to the physical prototype.
6. Feature-Based Modeling: The library enables feature-based modeling, wherein the design is constructed by adding and combining individual features. Each feature represents a specific geometric shape or operation, such as extrusion, fillet, or chamfer. This approach simplifies the design process and promotes modular, reusable design practices.
7. Customizable Workflows: CadQuery allows users to create custom workflows tailored to their specific design needs. By encapsulating design steps into functions or classes, designers can easily reuse and share their design processes across projects.
8. CAD Kernel Independence: The underlying use of the Open CASCADE Technology (OCCT) allows CadQuery to be CAD kernel independent. This means that the library can potentially support multiple CAD kernels in the future, offering users the flexibility to choose the most suitable one for their applications.
9. Active Community Support: CadQuery has a growing community of users and developers who actively contribute to its development and provide support through forums, GitHub, and other channels. This active community ensures that the library continues to evolve and improve over time.
10. Applications Across Industries: CadQuery finds applications in a wide range of industries, including mechanical engineering, aerospace, product design, architecture, and more. Its versatility and parametric capabilities make it an indispensable tool for professionals seeking to streamline their design workflows and enhance productivity.

Its integration with popular 3D printing and CAD tools further enhances its utility, making it a valuable asset across various industries.
By providing a Python-based scripting interface, CadQuery allows users to leverage their programming skills and work with familiar syntax to create intricate 3D models. This Python integration makes it easy for developers to automate design tasks, generate large-scale design variations, and conduct design optimization studies with minimal effort. The library’s open-source nature encourages collaboration, fostering a strong community that actively contributes to its development, and provides valuable assistance to fellow users.
One of CadQuery’s standout features is its parametric design capabilities. By introducing parameters into the design process, users can define variables that control specific dimensions or features of the model. This approach enables quick modifications and iterative design processes, as changes to parameters propagate throughout the model, maintaining design integrity. As a result, users can create design families with shared features or explore multiple design alternatives efficiently.
With built-in support for interactive 3D visualization, CadQuery facilitates real-time model inspection and manipulation. Designers can visualize their models within Jupyter notebooks or use integrated viewers like ParaView to interact with the 3D designs. This interactive feedback mechanism allows for a more intuitive and immersive design experience, aiding in the identification of potential issues and the refinement of the final design.
Furthermore, CadQuery’s feature-based modeling approach offers a structured and modular design workflow. Designers create models by adding and combining individual features, each representing a specific geometric shape or operation. This feature-based methodology simplifies complex designs, encourages the reuse of established features, and facilitates the modification of specific aspects of the model without affecting the entire design.
The library’s CAD kernel independence is another valuable attribute. By leveraging Open CASCADE Technology (OCCT) as the underlying 3D modeling kernel, CadQuery ensures that it is not tied to a specific CAD engine. This flexibility provides the potential to support multiple CAD kernels in the future, enabling users to choose the best-suited kernel for their specific needs or industry standards.
Moreover, CadQuery plays a vital role in bridging the gap between design and manufacturing. Its export capabilities to standard 3D file formats, such as STL and STEP, allow for seamless integration with 3D printing technologies and various CAD software used in the manufacturing pipeline. This integration streamlines the process from design to prototyping, enhancing collaboration between design teams and manufacturers.
Thanks to its customizable workflows, CadQuery empowers users to encapsulate design steps into functions or classes, creating reusable and shareable design processes. This approach promotes best practices, consistency, and efficiency across design projects and enables designers to build a library of design functions tailored to their specific domain or industry.
CadQuery finds diverse applications across industries, including mechanical engineering, aerospace, product design, architecture, and more. Its versatility makes it suitable for designing complex parts and assemblies, optimizing structures, and automating repetitive design tasks in various engineering disciplines.
In conclusion, CadQuery is a game-changing tool for parametric 3D modeling, powered by Python, feature-based design, and an active community of users and developers. Whether you are an engineer, designer, or developer, CadQuery’s user-friendly approach and powerful capabilities make it a valuable asset for streamlining design workflows, enhancing productivity, and unleashing creativity in the world of 3D design and manufacturing.
